In the Julian calendar, named after Julius Caesar, every fourth year had 366 days rather than 365. Roman astronomers calculated that a year — the time it takes the Earth to revolve around the sun —had a duration of 365.25 days. This method of adding a “leap day” every fourth year averaged out to this determined value. Except, a year’s length isn’t 365.25 days; it’s actually a bit shorter. This only became noticeable as the centuries passed and the calendar drifted out of sync with the seasons.
By the 16th century A.D., people noticed that the first day of spring had drifted 10 days ahead of the intended 20th of March. Basically, history had used a leap-day year 10 more times than was useful. Recognizing the 10-day error, Pope Gregory XIII had a scholar (Aloysius Liliusa) devise a new system that would keep the calendar in sync with the seasons. This new system changed which years should be considered leap years based on what numbers divide the years evenly.
Putting the calendar back in sync At the time, such changes were considered controversial, but not nearly as controversial as the plan to put the calendar back into sync with the seasons. The Pope only had the authority to reform the calendar of Spain, Portugal, the Polish–Lithuanian Commonwealth and most of Italy. In those regions, Thursday, Oct. 4, 1582 (of the Julian calendar), was followed by Friday, Oct. 15, 1582 (of the Gregorian calendar).

Right, I think I can pin down the problem to the fact that the site quoted is using the word ahead in a confusing way.
It says exactly the same things as everybody else on the difference between the two calendars, but it describes as "being ahead" what everybody else calls "being behind".

1257 years/4 leap year Julian = 314.25 days
1257 years/4.123 leap year Gregorian = 304.88
You can see there are more Julian days then Gregorian by a difference of 9.37 days.

Never does the Julian calendar drift behind the Gregorian. The calculations prove otherwise.

That's right.
And because the Gregorian average century has fewer days than the Julian average century, the Gregorian calendar gets to the end of the century faster, and is ready to start a new century earlier
You really need to make yourself a visual aid.
In effect, the Gregorian gets ahead because it has shorter distances to travel.

The Gregorian calendar did not exist at the time when the Mayan "long count" began, so that issue is irrelevant.
I will try to explain the mechanics again.
Let us suppose that the two calendars show the same date at the begining of a certain year.
And suppose that this one of the years which the Julian calendar counts as a leap year and the Gregorian does not.
Therefore the Julian year will have 366 days and the Gregorian year only 365.
In that case, the Julian 29th of February will be the Gregorian 1st of March, and the Gregorian calendar is ahead already.
The Juilan 30th of December will be the Gregorian 31st of December, and the Julian 31st of December will be the Gregorian 1st of January for the following year.
That happens every couple of centuries, and THAT is how the Julian calendar falls behind,
Abstruse calculations about what the Julian calendar ought to say are quite irrelevant, when we have living witnesses to what the Julian calendar actually does say.

The Julian was 10 days ahead of the gregorian. Your agruement somehow says that the Gregorian calendar would be 10 days ahead of the Julian calendar?
Why do Russian Orthodox Christians celebrate Christmas so much later than Western Christians? Because the Russian Orthodox Church still observes the Julian calendar. Dec. 25 on the Julian calendar corresponds to Jan. 7 on the Gregorian calendar, which America and most of the rest of the world uses. Currently, each day of the Julian calendar occurs 13 days after its corresponding day on the Gregorian calendar—therefore, Dec. 25 on the Julian calendar corresponds to today on the Gregorian calendar. (Although the Russian Orthodox Church still uses the Julian calendar, the Russian government uses the Gregorian calendar just like the rest of the world, so for secular purposes, today is Jan. 7 in Russia, not Dec. 25.)
"While Christmas trees and decorations have been taken down in many countries, celebrations are just beginning in others. In Russia, Ukraine, Greece, Israel and several other nations, Orthodox Christians, Greek Catholics and Coptic Christians will celebrate Christmas Wednesday 13 days after the well-known Dec. 25 festivities.
Because the Julian calendar has a leap year in all years divisible by four—without excepting centurial years not divisible by 400, the way the Gregorian calendar does—the discrepancy between the Julian and Gregorian calendar changes periodically. For instance, beginning in 2100 the difference will increase from 13 days to 14 days when the Julian calendar adds a day to that year, and Russian Christmas will then fall on Jan. 8 instead of Jan. 7.
Why is Christmas celebrated Jan. 7? The difference in dates goes back several centuries to when Pope Gregory XIII established the Gregorian calendar in 1582. The Gregorian calendar has become known as the “Western calendar” and is internationally followed by many governments with Christmas celebrated Dec. 25. The Gregorian calendar was introduced to correct the Julian calendar that was created under the rule of Roman leader Julius Caesar and dates back to 46 B.C. Not all religions have switched over to the Gregorian calendar, which accounts for celebrations on Jan. 7 ."
